CD4541
DESCRIPTION
The CD4541 programmable timer prise a 16-stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, output control logic, and a special power-on reset circuit. The counter divides the oscillator frequency by any of 4 digitally controlled division ratios.
- FEATURES
- Operates at 2n frequency divider or as single transition timer
- Increments on positive edge clock transitions
- Wide supply voltage range: 3.0V ~ 15V
- Built-in low power RC oscillator
- Oscillator frequency range ~ DC to 100 k Hz
- External clock applied to Pin 3 can be used instead of
- oscillator
- Available division ratios 28, 210, 213, or 216
- High noise immunity: 0.45 VDD (typ)
- Master reset totally independent of automatic reset operation
- Automatic reset initializes all counters when power turns on
- Q/Q select provides output logic level flexibility
- High output drive min. one TTL load
- Maximum input leakage 1μA at 15V over full temperature
